I am doing a course where we have a case on Bhopal Gas Tragedy. After reading the case we searched it on Google images and after one such image it was enough. The decision was conscious. After all business students should know about some of the worst manifestations of the industrial society.
The other staggering bit in this saga is that Dow Chemicals (that bought Union Carbide eventually) became sponsors of London Olympics. The heartening part, people in London protested.
I hope this is going to be a learning experience for everyone involved in the course.
